ENGLAND.

CARDlNG-ENGINE.

SPECIFICATION forming part of Letters Patent No. 388,679, dated August 28, 1888. Application filed January 4, 1888. Serial No. 259,791. (No model.) Patented in England July 24, 1884, No. 10,518.

To all whom it may concerns Be it known that I, J OHN MUIR HETHERING- TON, a subject of the Queen of Great Britain and Ireland, residing at Manchester, county of Lancaster, England, have invented certain Improvements in Carding-Engines, (for which I obtained a patent in Great Britain, No. 10,518, dated July 24, 1884,) of which the following is a specification.

My invention relates to the covering or inclosing casing of the upper part of the doffer and of the adjacent part of the main cardingcylinder of the carding engine, and has for its principal object to facilitate the adjustment of the parts.

In my invention the doffer-covcr is hinged to parts which can be adjusted upon the framing toward and from the main cylinder, the cover, when raised, moving away from the said cylinder. The making-up pieces are carried by the cover, and the hinges are situated at the front of the doffer-axis and at the same level, or at such a suitable level as that when the cover is raised all parts of the curved surface which are concentric with the doffer-axis move farther away from the doffer and the curved surface which is concentric with the main cylinder-axis moves away from the said cylinder. To enable the cover to be adjust-able independently of the doffer, I make the cover to fit at the ends upon flat surfaces which are parallel with the line of adjustment.

My invention will be understood when described with reference to the accompanying drawings, in which- Figure 1 represents a side elevation of part of the doffer end of a cardingengine, and shows an end View of the doffer-cover and a portion of the side casing of the engine. 2 is a view taken on a plane at right angles to that of Fig. 1, and shows the hinging of the doffer-cover and a part of the main frame in section.

In the said figures, a is the dofl'er'cover, and b is a side frame, which in this instance is a portion of the casing for the doffer and main cylinder on one side of the engine, the dotted circle 0 indicating the doiier and the dotted are d the main cylinder. The dofl'er-cover is attached to two side pieces, e, one at each end Fig.

ard, j, which is bolted or secured to the under framing, Z, of the engine. Thejoint-pins of the two hinges on the two sides of the engine are arranged to be in line across the engine, so that the two side pieces, 0, carrying with them the dofl'er-cover, can. be turned up andover, as indicated by the dotted lines. The side pieces, 0, also carry the makingup piece or pieces 9, so that when the doffer-cover is raised access is had to the main cylinder for grinding the same or for other purposes. Each standard is adjustable upon. the framing toward and from the main cylinder. The standard is connected by means of a screwed stud, h, with a bracket, 2', which is firmly bolted to the framing, and serves as an abutment or fixed point from which the standard can be adjusted by turning nuts on the screwed stud. When the adjustment has been effected, the standard can be secured by means of a bolt, 7c, passing through an opening in the lower part of the side frame is made parallel with the line of ad justment, or thereabout, and the side piece, e, rests upon. this level edge at the point Z, or is otherwise suitably formed to rest or fit upon the said upper edge, b, of the casing. It will be seen that by reason of this straight and level formation of the edge b and of the under sides of the side pieces, a, the doffer-cover can be set up or adjusted in a direction toward or from the main cylinder to any required extent without altering the relations of the cover and the side or end casings, b.

Having now described my invention, I declare that what I claim is- 1. In a cardingengine, the combination of the main and doffer cylinders, under framing, and side frames having flat or level surfaces,

'with the doffer-cover resting upon said flat or level surfaces, standards or blocks to which the dolfer-cover is hinged, and means for adj usting the said standards upon the framing, substantially as set forth.

2. In a carding-engine, the combination of the main and doffer cylinders, side frames, and

under framing, with the doffer cover and parts to which said cover is hinged in front of the main axis of the doffer, so that when the cover is lifted all parts move clear from the 5 dofl'er, substantially as described.

3. In a carding-engine, the combination of the main and doffer cylinders, under framing, and side frames having horizontal surfaces, in

combination with the dofi'er-cover, making-up IO pieces, and side pieces resting upon the said horizontal surfaces, standards to which the said side pieces are hinged, and means for adj usting the standards, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subl 5 scribing witnesses.
